Make it simple - A + B = 6 A - B = 2 (Adding both the equations) 2A = 8 A = 4 , that implies B = 2 A*B = 4*2 = 8

A+B+A-B=6+2=>8 2A=8 SO A=4 Similarly subtract both equation A+B-(A-B)=6-2; A+B-A+B=4, 2B=4 So B=2 ; Put A=4 and B=2 in A*B then we get 4*2=8 .

Hi Everyone. Just wanted to know that How you guys usually charge your students? Is it by "Per Hour" or "per Month" or for "Entire Course"? And if its is by "per Month" or for "Entire Course" basis, then How many classes do you take in a week?
I am always for for all the options to be chosen by the parents. "Per Hour" or "per Month" or for "Entire Course" based on that we share the cost. Usually five days in a week.
